3 Claims.

This invention relates to a novel package and to the method of producing it.

It is an object of the invention to produce a package which may be readily formed simply by applying the wrapper to the article to be wrapped and folding its parts into position; gluing'operations,.and previous pre-forming or blocking out of the wrapper being unnecessary. The package formed according to the invention will be of neat 1 and pleasing appearance, and will have no bulges in the wrapper to detract from the appearance ofthe package or interfere with its stacking with other similar packages; and the wrapper will effectively seal the article wrapped and will not be readily accidentally disarrangedbut can, if desired, be opened and reclosed without breakage. In one form of the invention all loose edges of the fold aremrotected and concealed by adjacent at the center of the package; and to provide such.

a wrapper wherein thegenerally radial fold sec 30 tions interlock, no auxiliary fastening means being required, and wherein the exposed creasesof thescctions are held in place by overlapping adjoining sections.- a portion or all of the wrapper at the end of each fold section lying under adjoinas ing sections.

Still further objects are to provide a package wherein the wrapper has symmetrical folds which may be produced by a single composite folding operation, and wherein the folds may be there- 40 after creased to hold them firmly in position.

' Other objects and advantages of the invention will be apparent from the following description of certain preferred embodiments thereof when taken in connection with the accompanying draw; ing. In the drawing wherein like reference numerals refer to like parts throughout,

This application is a continuation in part of my copending' application Serial No. 667,539, filed April 24, 1933, and my copending application. Serial No. 672,840, filed May 25, 1933.

In the drawing, referring first particularly to Figs. 1 to '1, inclusive, thereof, the wrapper by which the package of the invention. is formed. is

shown applied for purposes of illustration to a generally cylindrical article ID having substantially fiat end portions II. The wrapper I! which may comprise merely a rectangular sheet of paper of suitable size, no previous blocking or forming of the wrapper being necessary, is first wrappedabout the article circumferentially, the wrapper being of sufficient width so that the portions i3 and i4 thereof will overlap. Glue or other suitable adhesive may be applied to these portions to permanently secure them in position, although this is not necessary as the subsequently formed end folds will hold the wrapper in the completed The '3 wrapper is of'such length that it extends beyond each end ll of the article, as indicated at I! and IS, a distance equal to the radius of the article, so that when, the end portions are overlapped and folded upon the article end, they will meet, but 40 will not overlap at the center of. the article.

After the wrapper is formed about the article as shown in Fig. 1, the and folds are formed. These end folds maybe formed by the mechanism illustrated in my aforesaid copending application, SerialNo. 672,840. This mechanism for forming the folds-will not be described herein, however, as the folds may be formed by other suitable mechanical means or by simple manual manipulation of the wrapper.

comprises moying circumferentially spaced poritions of the wrapper end inwardly toward each In forming the end folds, the first step, as illustrated in Figs 2,

indicated by the reference character I'I. As the portions I! are moved inwardly, ribs I! are formed therebetween, the ribs becoming narrower as the depressed portions I'I approach the article end. The depressed portions II are moved inwardly along lines extending toward but not through the central axis of the tubular wrapper.

.That is, the portions are moved inwardly along lines which deviate somewhat from true radial lines of the package ends. Where the ribs l8 are to be folded over in a clockwise direction.

with the article ends and the folds thereon.

The package thus formed is shown in Figs. 4, 5, 6 and 7. As will be best seen from Figs. 5 and 7, the inner crease ll of each rib I8 is displaced counter-clockwise from the radial line A-B ex tending from the outer end ID of the rib, and the outer crease I8 is displaced clockwise from the radial line. In other words, the inner covered crease ll' lies to one side of the radial line of the rib, whereas the exposed or outer crease l8 lies to the opposite side thereof. The portion 20 of the inner end edge of the fold is, therefore, covered by the overlying adjacent counter-clockwise folds. The portion 2| ofthe end is exposed. However, this portion as well as the exposed crease l8 and the apex 22 of the rib are held tightly in position against the article end by reason of the engagement of adjacent counterclockwise folds over the end portion 20, as well as by reason of the fact that such adjacent folds overlie the fold body portion to a considerable extent.

The folds are all similarly formed, and each is overlapped by adjacent folds so that all the folds are interlocked and the entire wrapper end willbe held securely in position- The package is neat and there are no unsightly bulges to destroy its appearance. Moreover, the ends of the folds :lust meet, but do not overlap at the center of the article, so that no thick wrapper portion is formed at the center which will interfere with the stacking of the packages. The wrapper holds itself in position by reason of its formation,

and no auxiliary fastening means is necessary;

and the end portion can'be unfolded if desired, access being had to the article, after which the ends can be refolded without tearing them or otherwise impairing their efficiency. The folds are securely held in position by reason of thefact that a portion of the fold ends are covered.

In Fig. 8 is shown a modified form of the invention wherein the inner crease I4 is displaced further from the radial line A-B of the rib than .is the outer crease". In this form of the invention, the concealed covered portion 28 of the end of the fold is considerably greater, and the exposed end'portion 21 is correspondingly reduced. Thereis less tendency, therefore. for the folds to he accidentally loosened or displaced as; a greater portion of the exposed edges are con-' sealed and protected. However, a portion of the edges are exposed, so that the wrapp r may be readily unfolded. This form of package may be made as described with reference to the first embodiment of the invention, the depressed end portions of the wrapper merely being further displaced counterclockwise as they are formed. 5

In Fig. 9 there is shown a still further embodiment of the invention. In this embodiment the inner crease 29 is displaced from the radial line. A--B of the rib, the entire width of the rib, and the exposed crease 30 is coincident with the radial line. In this form of construction, the entire end 3| of the fold is concealed and protected underneath the wrapper. The only exposed edge is the crease 30, and this crease is anchored at its outer vend 32 to the cylindrical body of the 1 wrapper, and at its inner end 33 by reason of the fact that it is interlocked at this point with all of the other folds. There are, therefore, no loose edges which are susceptible to accidental displacement, the only exposed edge being se- 20 curely anchored at both ends thereof. Again,

the method of folding the wrapper ends issimilar to that previously described in connection with the embodiments of Figs. 1 to '7 inclusive,

it being necessary only to further displace the 25 depressed portions in counter-clockwise direction, as the ribs are folded-over.

It is obvious that various changes may be made in the particular embodiments of, the invention used for purposes of illustration, and in the method steps described in connection with the formation thereof. I accordingly do not wish to be limited to the precise embodiments or method steps shown, but only as indicated in the following claims. 3

-l. A package comprising a substantially cylin- I drical article, a wrapper therefor, said wrapper extending about the sides of said article with its longitudinal edges in at least meeting relation 40 and having a portion extending outwardly be-- yond the end of the article a distance equal to generally half the diameter of the article, said extending portion having a free edge, said extending portion being folded over the end of 45 the article, in a mannr to form circumferentially spaced pairs of fold lines diverging from points adjacent the circumferential edge of said article, each pair of said fold lines diverging from a single point, said points of divergence being 50 substantially equally spaced about the peripheral edge of said article, said fold lines defining spaced ribs, all of said fold lines intersecting said free .edge in sp d relation with each other, the midpoint of those sections of the said free edge between adjacent pairs of fold lines lying approximately in the axis of said article when said wrapper is in folded position and said overlapv ping ribs defined by said fold lines overlapping consecutively in the same direction.

2. The method of securing a wrapper about a substantially cylindrical article which comprises disposing saidwrapper about the sides of said article with its longitudinal edges in at least meeting relation and having a portion extending outwardly beyond the end of the article a distance equal to generally half the diameter of the article and having a free edge, and folding said extending portion over the end of the article along circumferentially spaced pairs of fold lines diverging from points adjacent the circumferential edge of said article, each pair of said fold lines diverging from a single point and intersecting said free edge in spaced relation with each tially equally spaced about the peripheral edge of said article to define spaced ribs, and as an incident to the folding step disposing said ribs in folded position with the mid-point of those sections of-the said free edge between adjacent pairs of fold lines approximately in the axis of said article, said overlapping ribs defined by said fold lines overlapping consecutively in the same direction.

'3. The method of securing a wrapper about a substantially cylindrical article which comprises disposing said wrapper about the sides of said article with its longitudinal edges in at least article, and simultaneously folding said extending edge over the end or the article along circumferentially spaced pairs of fold lines diverging from points adjacent the circumferential edge of said article and intersecting said free edge in spaced relation with each other, the fold lines of each pair making substantially equal angles with-the free edge when in unfolded position, said points of divergence being substantially equally spaced about the peripheral edge of said article to define spaced ribs, and as an incident to the folding step disposing said ribs in folded position against the end of the article with said ribs defined by said fold lines overlapping con-' secutively in the same direction.
